Abstract (en)

According to the present invention, there is provided a molding system ( 100 ) configured to manufacture a molded article ( 103 ) by using molding material ( 101 ). Molding system ( 100 ) comprises a mold-cavity system ( 200 ) for forming molded article ( 103 ). Mold-cavity system ( 200 ) includes a stationary-mold assembly ( 201 ) and a movable-mold assembly ( 203 ), defining therebetween a mold cavity. Movable-mold assembly ( 203 ) includes a base portion ( 202 ), a top portion ( 204 ), a neck portion ( 206 ), and a core portion ( 208 ). Stationary-mold assembly ( 201 ) includes a cavity portion ( 210 ) and a gate portion ( 212 ). Mold-cavity system ( 200 ) further includes a controller ( 160 ) operatively coupling to a mold-moving actuator. Controller ( 160 ) has a controller-usable memory ( 162 ) tangibly embodying a set of controller-executable instructions ( 500 ) configured to direct controller ( 160 ), and which include a mold-open instruction ( 902 ) configured to cause relative movement between core portion ( 208 ) and cavity portion ( 210 ) by a distance sufficient to displace the totality of molecules of plastic of molded article ( 103 ) that abut with core portion ( 208 ) from their relative positioning during a process cycle. The displacement is in substantially the same direction, while maintaining at least some of the clamping force.
